PHP捲曲下載

Question

我使用捲曲下載從位置文件

function get_data($url) 
{ 
    $ch = curl_init(); 
    $timeout = 5; 
    curl_setopt($ch,CURLOPT_URL,$url); 
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); 
    curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,$timeout); 
    $data = curl_exec($ch); 
    curl_close($ch); 
    header("Content-Type: application/force-download"); 
    header("Content-disposition: attachment; filename=zipfile.tar.gz"); 
    echo $data; 
} 

$rt = get_data('http://slackbuilds.org/slackbuilds/13.37/multimedia/umplayer.tar.gz'); 

這並下載文件，但我無法打開it.Is強制提正確的Content-Type？我正在使用這個腳本來處理視頻，所以我嘗試了Content-Type：Video，但仍然不適合。

Answer 1

設置CURLOPT_BINARYTRANSFER爲TRUE，並更改內容類型。

<?php 

$url = "http://slackbuilds.org/slackbuilds/13.37/multimedia/umplayer.tar.gz"; 
$opts = array(
    CURLOPT_URL =>$url, 
    CURLINFO_CONTENT_TYPE => "text/xml", 
    CURLOPT_BINARYTRANSFER => TRUE, 
    CURLOPT_RETURNTRANSFER => TRUE 
); 

$ch = curl_init(); 
curl_setopt_array($ch, $opts); 
$data = curl_exec($ch); 
$info = curl_getinfo($ch); 
curl_close($ch); 

header("Content-Type: application/x-gzip"); 
header("Content-disposition: attachment; filename=zipfile.tar.gz"); 

echo $data; 
?>

也許你缺少header("Content-Transfer-Encoding: binary");
